Hi,

I am testing PBS for a week now and am very satisfied with it. I am currently backing up 2 PVEs to one PBS. One of them is very low powered and has only so much disk space. When I try to back up a larger machine it fails after filling up local storage. Can I somehow set up a localtmpdir for backups using the new backup-client as it seems that vzdump.conf doesn't affect this.


Thanks!
 
I assume you are talking about container backups? which mode? can you post a full log of such a failing backup job?
 
hi fabian,

thanks for your quick response. You're right. It's a container. Here's the output of one of them:

yes, suspend mode backup needs to copy all the files to a tmp dir on the PVE host. either configure your container to support snapshot mode, or use stop mode, or set 'tmpdir' in /etc/vzdump.conf to somewhere with more space.

Hi Fabian,


i used snapshot mode in this example.

INFO: starting new backup job: vzdump 110 --node haruka --storage <redacted> --remove 0 --mode snapshot


Also the tmpdir actually IS my issue. The backup process seems to ignore the tmpdir option.
 
Same issue here: ERROR: Backup of VM 105 failed - command 'rsync --stats -h -X -A --numeric-ids -aH --delete --no-whole-file --sparse --one-file-system --relative '--exclude=/tmp/?*' '--exclude=/var/tmp/?*' '--exclude=/var/run/?*.pid' /proc/4181/root//./ /var/tmp/vzdumptmp48360' failed: exit code 11
